how to generate 3 phase sine wave to output on ELVIS

[ethen99]

Hi .I need to make a star or delta connected circuit on ELVIS board.2 make this circuit I need 3 wave generator( with 120 phase shift) and one common ground

and because the ELVIS function generator can only generate one wave I decided to generate countionuos sine wave in Labview.

Now I can generate 2 continuis sine wave in labview and output them on the analog outputs of ELVIS.Ao-0 and A0-1

but I dont know what to do for the third signal.the elvis board just has 2 analouge output and when I use  Ao-0 and A0-1 I cant use ELVIS function generator after that.so would u please help me on this problem.how can I output 3 contious sine wave in Elvis.I have attached my VI to this post

Hey,

Unfortunately there is no way to generate this 3rd wave from the computer - the ELVIS was designed with only two AO ports as there are a selection of DAQ cards which can interface to it which only have two analogue outputs. The only option I can think of is that you could perhaps use the breadboarding ability of NI Elvis to create some circuitry to generate the wave.

Kind regards,

Hi, I am also having some problem in generating two signals from two AO. Could you please tell me how to generate two different signals from two AO. I have attached vi which generate square wave from one AO 0. I need the inverted signal in AO 1.
